Slide2ObjectiveSWU: the locations and functions of the major parts of the male and female reproductive system SW: research the locations and functions of all major parts of the male and female reproductive system
Slide3The Male and Female Reproductive SystemsThe structures of the male and female reproductive systems are adapted for the production and release of the gametes (sperm and egg)
*Structure is ALWAYS related to function
Slide4Human ReproductionEverything comes down to a male gamete (sperm) fertilizing a female gamete (egg/ovum)
Ensures ½ genetic makeup of the resulting zygote comes from each parentEnsures genetic variation in the human species

Slide5Organs of the Male Reproductive SystemThe organs of the male reproductive system are specialized to:Produce and maintain the male sex cells (sperm)To transport sperm with supporting fluids (semen) to the female reproductive tract
To secrete male sex hormones
Slide6Organs of the Male Reproductive SystemMale primary sex organs:
Testes The other structures are termed accessory sex organs
Slide7The Male and Female Reproductive SystemsThe female reproductive system is specialized to:
Produce and maintain the female sex cells (oocytes)Transport oocytes to the site of fertilization (uterus)Provide an environment
for a developing offspringMove the offspring to the outside (childbirth)Produce female sex hormones (estrogen)
Slide8The Male and Female Reproductive SystemsFemale primary
sex organs: OvariesThe other structures are termed accessory sex organs

Slide10Male Reproductive System
Seminal vesicleProstate gland
Anus/ RectumEpididymisscrotumTestis
Erectile tissue of penisUrethraVas deferensUrinary bladder
Slide11Testis-
Produces sperm Form male sex hormone- testosterone
Contained within the scrotum
Slide12Fun Fact!!!Testes normally drop a month or two before birth, but may take as long as a year
Cryptorchidism is a disorder where the testes fail to descend into the scrotumMay need Undescended testicle repair is also known as orchiopexy,
within the first year of lifeIf left untreated, the cells that normally produce sperm cells degenerate and the male is infertile, because the temperature in the abdominal cavity is too hot
Slide13Critical Thinking QuestionWhat changes, if any, might occur in the secondary sex characteristics of an adult male following removal of one testis? Following the removal of both?
Slide14Epididymis- Tightly coiled tube connected within a testis
Support stored sperm cells Promote their maturationOnce matured, they can move independently and fertilize an egg
Slide15Vas deferens (ductus deferentia)- Muscular tubes
Transports sperm from epididymis to the urethra
Slide16Fun Fact!!!A vasectomy is an operation that makes a man permanently unable to get a woman pregnant. It
involves cutting the vas deferens so that sperm can no longer get into the semen.
Q. Will I still be able to ejaculate after vasectomy?A. Yes, semen is made in the seminal vesicles and the prostate gland. These are not affected by a vasectomy. Sperm make up only 2 to 5 per cent of the ejaculate so you will not be able to notice any difference in the volume of your ejaculate.Q. Will I still make sperm after my vasectomy?A. Yes, sperm continue to be made in the testes after a vasectomy. After time, however, production of sperm is often reduced.Q. After my vasectomy where do the sperm go?A. The sperm, which are made in the testicles, cannot pass through the vas deferens once they have been cut and tied, so they are reabsorbed by the body.
F.A.Q:
Slide17Seminal vesicle- Saclike gland attached to vas deferens
Secretes an alkaline fluid that makes up 70% of semen
Helps regulate pHContains fructose which provides energy to the sperm cellsChemical which stimulates muscular contractions within the female reproductive organs, aiding in the movement of sperm cells toward the egg
Slide18Prostate gland- Chestnut-shaped gland that is inferior to the bladder
Connects the seminal vesicles to the urethraSecretes an alkaline, milky white fluid that makes up the remaining
30% of semenEnhances the motility of spermHelps neutralize the acidic secretions of the vagina, helping to sustain sperm cells that enter the female reproductive tract
Slide19Scrotum-
Sack of skin that contains the testes, epididymis and part of the vas deferensExposure to cold stimulates the muscles to contract, and the testes to move closer to the pelvic cavity
Warmth stimulates the scrotum to hang loosely Provides an environment about 5° F below body temp
Slide20P
enis- Cylindrical organ used for reproductionConveys urine and semen through the urethra to the outside
Erectile tissue of penis- Tissue with vascular spaces to be engorged with blood for erection
Slide21Urethra-
Tube connected to bladder for excretion of urine and semen
Slide22Female Reproductive System plus bladder
Oviduct aka Fallopian tubesOvary
UterusVaginaCervixVulva
Endometrium
Slide23Ovary-
Female reproductive organ in which eggs (oocytes) are produced
Forms female hormones estrogen/progesteroneLocated on each side of the pelvic cavity
Slide24Fallopian Tubes (Uterine tube or oviducts)-
Tube through which an ovum (egg) passes from an ovary to the uterus
Slide25Fun Fact!Tubal ligation or tubectomy a.k.a. having one's "tubes tied
" (ligation) is a surgical procedure for sterilization in which a woman's fallopian tubes are clamped and blocked, or severed and sealed, either method of which prevents eggs from reaching the uterus for implantation
Slide26Critical Thinking QuestionIf a woman who is considering having tubal ligation asks, “Will the operation cause me to go though my change of life early?”, how would you answer?
Slide27Uterus- (womb)
Hollow, muscular organConnects cervix and fallopian
tubesReceives the embryo that develops from a fertilized eggFetus develops here
Slide28Cervix-
Lower part of the uterusO
pens to the vaginaOpens for childbirth
Slide29Endometrium: blood-rich, inner mucous membrane of the uterusSheds during menstruation
Slide30Vagina-
Tube that extends from the uterus to the outsideReceives erect penis during sexual intercourse
Open channel for offspring during birth
Slide31Vulva-External portion of reproductive system
Composed of the structures that surround the openings of the urethra and vaginaLabia majoraLabia minora
ClitorisVestibule (opening to vagina)
